To all whom it may concern Be it known that I, FERDINAND PANY, a subject of the Emperor of Austria-Hungary,

`the impact is yieldinglyl taken up and the and a resident of New York city, in the county of New York and State of New York, have invented certain new and use ful Improvements in Machines for Molding Dolls Heads, of which the following'is a specification.

This invention relates to machines for molding dolls heads, and is particularly directed to improvements in the construction of the mold itself and the mounting thereof upon the machine. `j The principal object of this invention is which will make it possible to operate the machine at a higher speed and vto increase vthe output'thereof.

The material used in molding dolls heads isA ya composition which mustA be worked while hot, but the diiiiculty has been that as soonv as the mold attained the temperature of the compositiom'the latter would adhere `to the walls of the mold, so that it was diiiicult to remove the molded article until the mold cooled off. This,A of course, ren'dered the operation of the machine very slowand cut Vdown its output, heat of the summer months when the mol itself vis at a comparatively high temperal Another difiiculty has been experienced in connection with the operation of a machine of this character consisting in the deterioration of the mold sections'at their meeting edges, 'due to the v hammermgoccurring when the portions of the sides of the mold the mold are forced together. This `further reduced the speed of the machine, as-it was necessary to cause the sections to approac especially during the d thereof.. vThe upper section 1'6'of the moldv 'is attached' to a plate 21, fixedto va. cross each other very slowly to avoid'in a meas- To overcome these difficulties, I provide in the body of each section of the mold a cooling chamber throughwhich the water circulates to cool and maintain the same constantly at a low temperature. This chamber is formed with an inlet and outlet whichl areV connected by flexible pipes to 'of the machine.

some source of supply andl to a drain 'whereby the cooling medium is constantly during the operatlon' the mold Also the mold is so mounted tht it may move yieldingly' under the actioxif the machine, so that the force of supplied to hammering avoided.

Various further objects and advantages will more .fully appear from the detailed description. j l

In'the drawing illustrating this invention, .Figure l 1s a diagrammatic elevation, partly 1n section, of a machine bearing a mold em? bodying the invention.. Fig. 2 is a longif tudinal section of lthe lower mold member.,k Figs. 3 and 4c are sections taken respectively.

which 'is connected a'crank 13, actuating through a'connecting rod 14, the' members'irij 15 and 16 of a toggle. The mold proper' consists of' two sections -16 and 17, one of' section 17 is mounted upon a table 18 fixed 'l to the cross head 419,1g11idzed upon two posts 20, located. on either, 'side ofthe mold and attached to some stationary Vpart of the framework. The cross head is actuated upward by the toggle to'c'ompress the material in the mold so -as to conform to the contour bar 22, also mounted upo'n the guide post 20 -1 and held upwardby a spring 23, against the collar 24 attached to the upper end of' the post. This spring serv'esfto lessen the abruptness with which the mold sections 'aref parted when the doll'hasbeen compressed into shape.

I will'now describe the iinproved construc- 'j hl tion and mounting. of -the moldA sectionsl vwhereby the output of the machine'V as well as i the life of the mold itself are -greatly'increased. Referring 44:, it will be noted that'the -bottom.portion particularly to (Figs. 2, 3,

of the mold is formed with the interior form' portion 25, from which extends-the sleeve 26 for receiving the. core 27. Between the fiat bottom portion 28 of the mold and the form portion 25 is a recess 29 extending along the" sides ofthe mold and continuingl the Vpassage 30 formed under the sleeve 26. 'e

lThis recess is converted in'toa closed' com' through duit or chamber by the' cover plates 31 at' each side, and cover .plates'-32 :and 33. at .the 110 75 which, inthe present construction the lower one, is 'actuated 'by the toggle. `Thus,'the

ends ofthe/mold. A partition' Wall 34 is formed preferably at the end" opposite the handle of the .core 27 for dividing the cond uit into inlet""anddischarge sides... An in'- -let` nipp1e35 may thus enter the plate 33 at.

one side ofthe partition 34,- and a 'discharge .nipple 36 extends from the plate 33 at the oppositeside ofthe partition 34.* -Alexible pipe 37 conducts the coolingl liquid to the inlet from. some'suitable-source of supply, asthe water pipe`38, and another flexible pipe 39 conducts the liquid from the dis- .charge '36.. to some suitable .drain ,40. The upper section' of the lmold is similar .to the lower 'section in mechanical'detail's above dscribed, and'thus.l comprises the form portion a sleeve -portion26a, top 28 and the 'Y passage 299-430, closed by the side plates 31 and theend plates'similar to thefend` plates32 and 330i the bottom section. Flexible pipe sections 3 7a and 39Sv conduct the in.-

c'olning and the outilowingvwater respectively from the Water pipe 38 into the-4 drain-40.

' y"whereby the hammering'of `the mold sections is `el' I will Vnow describev the=improved -means inated and the life thereof vaccordinglyl prolonged.

plate 41 vWhichslides liiigiiides upon the table 18. Between'the plate 41--and the bottom of the mold .section isinterposed a lin-- 42 of someresil'ient material such as rubi' ber -or the like, which forms a yielding cushion and takes up the impact against the mating mold section, due to the rapid action of the skilled operator being able to determiney quite exactly ythe amount of material necessary to make up the head of the doll, so that mere is very slight, if any, overcharge or undercharge. The core thus encircled with tlfe heated plastic material is then placed in ythe mold and compressed intoshape. Dur-l ing this operation, the water lflows continu- .ously through the water. jacket to; cool the charge for the purposes above mentioned. l

It will be seen from the above descri tion that Ijhave provided an improvedmol and mounting therefor 'which can be used in a rapidly acting machine to obtain a large output per machine without lencountering any difficultyv in removing the material from the member to applg mold and withoutl injuring the parts of the latter,l due to the hammering hithertov encountered. I have found'that where previously only heads va day could be ro'- duced, I now produce with the same mac ine 450 heads without the slightest injury to the mold. The material comes out easily, -as- Y .not only does-itnot adhere to the walls of the mold byreason of .maintaining the latter'at a low temperature, but alsojth'e meeting edges ofthe mold sections are kept intact by the improved mounting and the material does not Wedge in ashas happened with the molds' hitherto used. The previous difficulty of Wedging was due t0 the upsetting of the A `metal' along theedge's of the mold by reason ofthe pounding or hammering. It will be seen' that according entirely eliminated.
